What does a fan speed sensor do?
Fan speed sensors are used in vehicles for two purposes. Vehicles with a fan clutch use the fan speed sensor to make sure the fan is running. Vehicles with an electric fan use the fan speed sensor to ensure the fan speed coincides with the fan speed that the Powertrain Control Module (PCM) requires.
What is code P0483?
What the P0483 code means. The ECM, or Engine Control Module, regulates the electric cooling fan within the engine. If the P0483 code is stored, it means that the cooling fan has been commanded to turn on or off, but the voltage reading indicates that the fan did not respond to the command.
What is code P0217?
The P0217 code means that the engine is or was overheating and should be turned off as soon as possible. Most engines have an engine coolant temperature sensor that sends a voltage reading to the powertrain control module which converts that into a temperature.
How do I check my fan clutch?
To confirm the diagnosis, start with this simple test: Spin the fan as hard as you can on an engine that has not been started that day. If the fan rotates more than five times, you can bet the clutch is bad. You should feel some resistance and the fan may spin up to three times, depending on the ambient temperature.
Can a fan clutch be repaired?
While there are times you can repair the fan clutch, in most instances it’s best to replace it. Your engine may have a hard time cooling down (overheating) or heating up since the fan clutch isn’t working.
What does the p0526 code on a fan speed sensor mean?
If the code returns, they have successfully diagnosed a larger issue with the fan speed sensor circuit, and should move on to other repairs. In some cases, a reoccurring P0526 code is due to a mechanic replacing the cooling fan motors without performing a more thorough diagnosis.
What does the p0526 code on a PCM mean?
In order to maintain proper powertrain cooling requirements, and to reduce the cooling fan noise as it is in use, the PCM uses a signal from the cooling fan to assess its speed. If the speed of the fan is higher or lower than the manufacturer’s specifications, the PCM will store the code P0526.
What causes a p0526 code on a Honda Civic?
Potential causes of a P0526 code include: Open circuit in cooling fan sensor harness or loose connection Fan clutch equipped – Visually verify the fan is spinning while the engine is operating. If the fan is not spinning, this may be caused by a broken accessory belt or a failed fan clutch assembly.
What is the DTC code for fan speed sensor circuit?
P0526 is a diagnostic trouble code (DTC) for “Fan Speed Sensor Circuit”.
